[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] This utility model relates to a speed measuring device for an aerial passenger transport system. It includes a photoelectric encoder 14 connected to a speed control circuit, the output of which is connected to a speed display screen 12. The device comprises a crossbeam 1, a mounting suspension 2, rope pulleys 3, and a speed measuring device 4. The lower part of the mounting suspension 2 has a pair of connecting plates 7, and two rope pulleys 3 are positioned between the two symmetrical connecting plates 7. The steel wire rope is lifted and held in close contact by the two sets of rope pulleys 3. As the steel wire rope travels, it rubs against the rope pulleys 3, causing the rope pulleys 3 to rotate.

[0027] The mounting suspension 2 of this device includes a T-shaped plate 5, a fixing clamp 6, and a connecting plate 7. The fixing clamp 6 is installed on the crossbeam 1. The upper part of the vertical portion of the T-shaped plate 5 is located at the lower end of the fixing clamp. The side of the horizontal portion of the T-shaped plate 5 is connected to the connecting plate 7. A fixing plate is located at the upper end of the T-shaped plate 5, with through holes drilled at each of its four corners. Nuts are connected to the lower end of the fixing clamp 6 through these through holes. One side of the horizontal portion of the T-shaped plate 5 has a through hole that mates with and is fixed to the connecting plate on that side. The hinge pin on the support rod 8 is connected to the connecting plate 7 or the T-shaped plate 5. The crossbeam 1 of this device is fixed to the roof of the tunnel.

[0028] This device achieves speed measurement by rotating the rope-supporting wheel 3. Since the rope-supporting wheel 3 is a steel wheel, it is inconvenient to install a sensor, so a speed measuring device 4 is added.

[0029] Specifically, the speed measuring device 4 of this device includes a support rod 8 and a speed measuring wheel 9. The lower end of the support rod 8 is connected to the speed measuring wheel 9, and the upper end of the support rod 8 is hinged to the connecting plate 7. A spring 11 is provided in the middle of the support rod 8 and connected to the connecting plate 7. The spring 11 pulls the speed measuring wheel 9 at the end of the support rod 8 to make tangential contact with the outer edge of the rope wheel 3. The steel wire rope 10 of the aerial passenger-carrying device is laid on the rope wheel 3. The speed display screen 12 is fixed on the side of the installation suspension 2 facing the direction from which the passenger comes. The speed measuring wheel 9 is equipped with a photoelectric encoder 14.

[0030] The passive rotation of the rope wheel 3 drives the speed measuring wheel 9 to rotate, and the photoelectric encoder 14 measures the rotation speed of the speed measuring wheel 9.

[0031] In this device, each of the rope-supporting pulleys 3 has a groove, and the wire rope 10 is placed in the groove of the rope-supporting pulley 3.

[0032] This device also includes a warning light and a power module. The warning light is connected to the speed control circuit, which is an LPC2214 based on an ARM controller. The power lines for the speed control circuit, photoelectric encoder, and warning light are connected to the power module. The circuit diagram is shown below. Figure 5 As shown, the specific circuit diagram is as follows: Figure 6 As shown, the display module is equipped with a driver circuit for driving display control.

[0033] The photoelectric encoder 14 measures speed by outputting a fixed number of pulses per revolution of the speed measuring wheel 9. The number of pulses per unit time is the rotational speed within that time period. The specific speed value is then displayed on the display module. Passengers of the aerial passenger transport device can see the operating speed at any time.

[0034] The speed control circuit will also compare the current speed with the alarm speed at any time. If the current running speed is greater than the set alarm speed and exceeds the set alarm delay, the alarm module will output an alarm signal and the alarm light will flash.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
